Last night I forgot to bring the tripod, but the mount head! Luckily u share the mount with me, otherwise I would waste the beautiful night!!! Anyway, the auto guiding was excellent last night. We shoot more than 3 hours & all of the frames showed no tracking problem! LVI guided excellently last night! After reflection, I should not use a 60mm small scope last night , because it was a waste. I should use my 80mm or larger scope instead...
Back to ur photos, apart from the spherical aberration of camera lens at the corners, the tracking was good. It is a good start, the next challenge is move up the focal length and see if u can guide up to 1000mm!!!

I still thinking why you didn't use your Equinox. Maybe next time, the sky will tell us.
Tonight, I will going to process your CAMERA's Raw and sharing the experience with you.

Next time, saving up much more money to buy a modified camera or my old one (300D).
Next next time, set up the Newtonian .......... :~~~~. (Last night,we wasted so much time to calibrate .....)

很高興昨天的Star Party看到Lewis自動導星開光成功，有能力把照片質量帶上另一台階了

導星就是這麼簡單，純粹一個回輸訊號而已。

談及攝影鏡頭，我個人看，日後若真的要換，數千元的短焦折射鏡也會比同焦距的昂貴鏡頭星點要銳利。

目前你和Willis好好用我的130/650攝星牛反拍些照片吧，稍後出一個測試報告就是了

Of course, when the sky tell us, we will going to take the photos.
